Mystery Detective Game Online - Harry Quantum 4: Doc Star

Rating: 7.8/10 - 464 votes

Discover the “Loch Bess” Monster, figure out the whereabouts of a missing rock guitarist, and more… It’s all in a day’s work for legendary online private investigator, Harry Quantum!

Harry Quantum 4: Doc Star is a wacky, point and click hidden object-themed game and analytical thinking adventure puzzle for older kids / teens where you must use good logic and strategy in order to solve the mystery disappearance of Doc, the missing guitarist from the popular rock band ‘Corned Beef Owls’.

Traveling to the site of the famous ‘Loch Bess’ Monster, you must use your point and click expertise to piece together clues and quirky objects to help reveal the Monster, and the location of the missing rock star (Believe it or not!).

This really eccentric and highly-challenging sequel in the popular Harry Quantum series of mystery adventure brain-teaser games requires keen eyes, smart analytical thinking and strategy, and a very inquisitive and tenacious mind (just like a true detective in real-life) willing to think outside of the box! You must be prepared to display great patience and concentration at all times, and make logical decisions about combining objects that you find. Happy sleuthing!

How to Play: After receiving a ‘Mayday’ postcard, Harry sets off to the last known whereabouts of the ‘Doc Star’ – Loch Bess castle. Here, you must interact with the scene in the game by clicking on a variety of items and objects, and hopefully discovering a pattern that helps to solves the mystery of the missing rock guitarist.

Using your computer mouse or touchpad, Left Click on any interesting object or character on the game screen. You can move any objects that you find into the boxes at the bottom of the game screen for future use. Also, click on two of the ‘found’ items to see if they can be combined together. Continue searching for and combining clues and objects until the mystery is revealed. You just never know when a clue might pop up!
